As an example, I created this same entry in the demo logbook using Safari.  As you can see there, the message is wrapped at the width that I set the text entry box.

> When creating new logbook entries, recent versions of firefox somehow ignore the message width setting.

> For example, configure a logbook with:
> Message Width = 76
> Message Height = 20
> 
> Then, create a new plain text entry that contains very long lines.  The text entry box is the correct size, but once you hit submit and view the full display of the message, it is not wrapped properly.  The summary display is wrapped properly, but not the full display.

> We've only found this to be a problem with recent versions of firefox.  Chromium, Safari, and old versions of firefox behave properly.
